tmax films are weird ...
i shot a boatload of 100 and 400
when i did newspaper work. 100 blocked up like mad with flash
400 was sweet.
they aren't fussy, i just don't like the uv layer in the 400 speed, it takes forever to contact print.
they both look beautifully grainy when souped to max density in coffee.
if xxx isn't an option, i'd go for neopan its very nice
